Sony A99 ISO6400 RAW files look spectacular....

I've been working with several high ISO RAW images and I have to say that I am very impressed with what the A99 files have to offer. From what I've seen, the ISO6400 are substantially better than the Pentax K-5 at the same sensitivity.

Keep in mind that this image was processed with default settings, and that output will likely improved with discrete processing.
